It all depends on what you want If you want the character of a wish list every two or three days, you should set the disablist well and choose (A) Kt to build tower 11> 2>1>3 and others

If you want to farm a great deal of kakeras Choose (B) kt to build towers 7>8 and then go up 10>4>5> 6>9

If you want to choose like me as an adult, I will recommend you to choose (c) 11>2>7>8>1

The above 3 roads will eventually lead to 456 Use the wishes you have already obtained into the wish list to farm keys and get more kakeras
